Clutch Slipping Per Dealer 2019 RT - does this sound right??
My 2019 RT SE6 with 27,000 miles on it is at the dealer for a symptom I would call surging when pulling away from my garage in the morning. I ride 35 miles to my first stop and turn it off. The rest of that ride after multiple stop and go or stop to eat the trike is ok. The dealer is telling me that the cutches are slipping and may need replacing at $650 labor plus parts. The oil level is ok and fresh. I always warm the trike up before pulling away in the morning. Clutches are under warranty so this will be an expensive bill to me. I would be glad to hear the forums opinion.
Proceed with knowledge and care
The SE6 is a fairly complex transmission say around 1990s automatic transmission technology level. And it uses a carefully modulated pressure to engage the motorcycle-style multi-plate clutch.
First, if you don't have a service manual, buy one and read the relevant sections -- there are several.
Second, to establish a lubrication baseline change your oil and both filters using BRP parts and lubricant. Another member opened his HCM filter -- I've lost his post but you should search for it. It included pictures so you know what to expect.
Third, check with your dealer to confirm you have the latest ECU and TCM firmware; that it is not corrupted; and to reset the long-term trim values.
And then see what you can learn from my thread https://www.spyderlovers.com/forums/...tul-7100-15W50
dg110270's shift issue sounds like flare
dg110270 -- the shift issue you describe sounds more like "automatic transmission shift flare". Here's an example article https://www.ipdusa.com/Articles/678/...r%20engagement.
If the article is applicable to your issue, the good news is you don't have to replace the clutch plates. The bad news is you have to replace the HCM (it apparently isn't repairable).
From the 2014 Service Manual
Quote:
The gear shifting and clutch clamping system of the SE6 engine is map-controlled by the transmission control module (TCM).
The transmission control module (TCM) manages 4 solenoid valves located on the hydraulic control module (HCM).
These solenoid valves command pilot pressure to actuate spool valves which are installed inside the HCM. The spool valves allow opening and closing of connections between hydraulic channels by using longitudinal control forces.
Unless your engine/transmission oil was contaminated somehow thereby wearing the spool valves, I think replacing the HCM is many miles and years in your future.
However you describe the issue as "surge" which sounds more like an engine rather than transmission issue.
So here's the question: at what RPM does your clutch begin to engage for pulling away from your garage and at what RPM does your clutch begin to engage after your 35 mile ride?
If they are about the same RPM then it's more likely an engine issue. Otherwise a transmission issue in which case start with my first post in this thread.
If you read my thread, my first-of-the-morning shifts were butter smooth (I pretty much drive away shortly after starting the motor) but when the engine heated up I would occasionally observe upshift flare and harsh downshifts. Switching to Motul 7100 15W50 helped immensely but I am not recommending that as your solution.
PS I don't have cold engine stumble. The 1330cc engine is a sweetie.
